30 HP at 480 (3 Phase) - 746 multiplied by 30 = 22380
22380 divided by 480 (3 Phase) = 46.5
46.5 divided by 1.73 = 29.5AMPS
Motor speed and efficiency may change the actual result. Always refer to the name plate data
20 *746 = 14.920 k.W
i = 14.92 k.w / v * p.f * root(3)
=25.9 amp
25.9 * 150% = 38.85 AMP

The above question can not be calculated because the voltage of the motor is not given. For code rule proposes a 20 HP motor at given voltages are, 200 volts = 62 amps, 230 volts = 54 amps, 460 volts = 27 amps and 575 volts = 22 amps. For wire sizing for motors always use the motors nameplate rating.

Read the specification plate on the motor to determine the amount of current that the motor uses, as well as the voltage and phase. Most likely, it will be a 3 phase motor, so you can't simply connect it to your house wiring, but without sufficient information, it is impossible to tell you all of the specifics. <<>> The code book rates the amperage of a three phase 40 HP motor by different voltages. at 200 volts - 120 amps, 230 volts - 104 amps, 460 volts - 52 amps and 575 volts - 52 amps. A breaker for a motor has to be sized to 250% of the motors full load amps. Also the wire size for a motor has to be 125% of the motor full load amps.
depends what the source voltage isone horsepower equals to 746watts (assuming 100% efficiency)746 watts divided by voltage source equals current (amps)AnswerIn countries, such as the USA, where the horsepower is still used as a means of measuring power, it is always used to measure the output power of a motor.So, in order to determine the current drawn by the motor, you will first need to find out its input power. The input power is the output power divided by the machine's efficiency. Once you know its input power, then you can find its current by dividing the input power by the supply voltage. In practise, you will need to use a wattmeter to determine its input power.
Need to know the voltage of the motor.

The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
about 3 or 4
481 amps if the load has a power factor of 1, but if the power factor is less than one (e.g. if it's a motor) you also have to divide by the power factor.
1.73*480*22
The formula you are looking for is Amps = kW x 1000/1.73 x E x pf. Use .84 for a power factor value.
The electrical code book states that a 40 HP 230 volt three phase motor draws 104 amps. For that motor the wire must be rated for 131 amps, Non time delay fuses at 300 amps, time delay fuses at 175 amps or a 250 amp circuit breaker. When calculating wire sizes and motor protection the motor's full load amperage should be taken from the motor's nameplate.

To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
